Review comment:
There is some history here. During our first release we found that RocksDB
is also shipped by YARN. That version of RocksDB is very old, hence this call
would fail in mysterious ways. @arp7 went and fixed that issue and made sure
that we don't enable this by default. I am fine with enabling this, if we don't
run into that old issue again. @elek, @arp7 any comments ?
